Product Description

Product Description

SP291 is a two-component polyurethane potting compound, the A component contains hydroxyl groups, and the B component is based on isocyanate. After A and B are mixed, they will form an elastomer after curing, and the volume will not change significantly.

Key Features:
1. Low hardness, good elasticity, excellent earthquake resistance;
2. Good sealing, waterproof and shockproof effect;
3. The product can be cured between 15-65 degrees without bubbles.
4. Excellent electrical insulation, flame retardant grade UL94 V-0, peelable and easy to repair

Typical Applications:
1. Electronic circuit board (PCB);
2. Electronic and electrical controller;
3. IGBT potting, new energy vehicle electrical controller potting, etc.
4. It can be used for filling, coating, casting, metal and plastic bonding well.
5. Used in communication equipment, transformers, control power supplies, ignition controllers, electronic sensors, etc.
6. Suitable for charging pile potting.

Packing and Storage:

Part A: 27 kg

Part B: 27 kg

Storage period: Part: 12 months; Part B: 9 months (sealed and unopened).
